The actual problem of electrification of the spacecraft surface is subject to research. Due to the direct impact of both positive and negative ions on the ship's skin, an electrostatic discharge can form, which can lead to equipment failure or to the complete failure of individual parts. To solve this problem, it was necessary to present information on the pattern of current spreading over the surface in a matrix form. The choice of the sparse matrix storage format and the implementation of several universal express methods for working with the received data will also be an important issue. To further describe the selected algorithms, an important step was to divide the problems into subtasks and justify each of them. As an example, the storage formats of sparse matrices and the compilation of mathematical modeling in the form of a schematic image of information were considered. The following requirements were presented for each of the subtasks: the effect of the used memory on the system load with an increase in the amount of data in the matrix; the mathematical justification of the subtask; the effectiveness of the mathematical model in describing the data used. Report volume on graduation work – 50 pages. The number of tables – 4, illustrations – 11, references – 32.
